There are many different considerations for any selection of materials, and one of the considerations is always how the valve or component is designed to work in a specific application. There are applications where a general type of ball valve is all that is required for shut off control, but in specialized applications, such as refrigeration systems, it is critical to use a specially designed valve.
A refrigeration ball valve is usually designed for bi-directional flow. Some types of general ball valves only allow one directional flow through the valve. This difference in design allows for a more compact system with the ability for the movement of the media either way, rather than running two sets of lines in the equipment.
While the refrigeration ball valve is designed to manage the actual refrigerant and to avoid any type of reactivity or corrosion with these fluids, they are also used in the hot lines in a system as well as for liquid and suction applications. As all of these diverse requirements are found in refrigeration applications, this makes this type of ball valve a highly efficient choice.
In commercial refrigeration equipment, as well as industrial applications in the food and beverage processing industry as well as the pharmaceutical production industries, high-pressure tolerances are critical for any refrigeration ball valve.
To withstand this type of high pressure, the valve itself is designed and fabricated using state-of-the-art welding on the body to create a leak-proof valve that has a long duty cycle. The choice of the seal material used in these valves is also critical for a leak-proof valve. The seal material must be able to stand up to the demanding type of application and not become hard, damaged or eroded due to high pressure and various temperature considerations.
